IMPROVEMENT IN DEVICES FOR LUBRICATING, COOLING, AND WASHING VERTICAL HAMMER-SHAFTS OR STAMPS.

The Sched-nie referred to in these Letters Patent and making part cf the sameA I, Z. E. GOFFIN, ol Newton, in the count-y of Middlesex and State of Massachusetts, have invented certain Improvements in Stamping-lilachines, ot' which the following is a specification.

Nature mul Objfcis of the Invention.

The nature of my invention relates to the Inode and means i'or supplying water to stamping-machines l'or the purpose oi' lubrication and excluding dust, dirt., and heat from the wearing-parts, so reducing friction and supplying wafer' to the material operated on by the stamps, as more fully set forth below.

Description of Drawings.

Figure 1 represents iri -a sectional elevationa series of stamp-shafts, AiB C, and related parts.

Figure 2 is a sectional plan of' those related parts.`

Figure 3 is a sectional view, embracing one of' t-lre stampslral'ts, and is taken transversely to the first.

Figures 4 and 5 illustrate, by sectional views, the application ol' the improvement to stamps already built withoutit.

Figure 6 is a. plan ofthe same.

Figure l shows, at e e, a`rnodica1ion of the same, which part is super-linens to the main illustration in that ligure. y

The stan'rp-shafts shown are. of' dili'erent varieties of' form and size, to show the adaptability of' the invention.

A is a large cylindrical shaft;

B is a smaller one ot' siruilar i'orrn while C has a square or angular section.

These stamp-shafts are guided in their up-and-down stamping movement by suitable bearings, such as shown in the drawings, or others of approved construction adapted to the purpose.

These bearingsare provided with a water-channel, a, so constructed and arranged about thc stamp-shaft and provided with an orifice or series of orilices, so arranged as to deliver water into contact with the stanrp-slralt-uprui all sides in suitablequantity to keep it entirely and constantly wet or lubricated when in imm-ation, so i'ar as they come into i'rictional contact 'with the bearing.

One entire annular or continuous orifice, as illustrated in ligs. 1 and 3, maybe used, or a series of small orilices, such as are indicated near e e, fig. 1,

may serve to keep the sha-ft approximately il' not entirely surrounded with owiug water'.

For the purpose of' supplying water to the channels a a or e e, a pipe or conductor, as I, figs. 2 and 3, or as shown in fig. 6, is arranged to connect these chan nels directly or indirectly by branches.

Tater is supplied to the pipe I by pumps, or by any convenient means affording suitable pressure.

' When applied to stampingmachines already built, in which provision has not been made for the application of the improvement, the channels d are rnadc separately from the frame of' thc. nrachine, as illustrated at e c, tig. 1, and in ligs. 4, 5, and 6.

The bearings above the channels a should, if not ol' such closeness and length as to prevent the escape ol' too nruch water in the upward direction, be' provided with some suitable packing for that purpose.

This packing may be ot leather' or other suitable material, applied in the manner' illustrated at c, figs. l and or in other well-knowrr methods used for similar purposes.

The dust arising from orcs and other material in the stamping process, will, by the constant issuing ot' water from or at the entrance of' the bearings on all sides, be prevented from getting into the bearings or guides, the bearings or guides will be kept cool, and the friction and wear will be greatly reduced, while the hearings or guides are thus constantly and effectually lubricated, which also tends directly t0 the same.

result. The water so used flows downward to the material in process ot' stamping, and so furnishes the supply l'or properly wetting or washing that, as may be required.

Claim..

An annular or horizontal groove in a cylindrical or other-shaped bearing or guide. in which moves vertically a shaft, said groove having a channel 0r channels for the influx ot' water under a pressure, the shaft moving loose in its bearir g or guide below the said groove or grooves, so as to permit the descent of' water suficient to wash downward all debris and to cool and lubricate the shaft.
